Both versions have the same music and artwork. The only difference is that Dismal Cursings' version has pro-printed cassettes, while the US version has a sticker on the cassettes instead and includes a patch.
The Crepúsculo Negro reissue comes on a clear tape, without stickers and patch.

Read through the comments on the first page. The reasoning is hardly conclusive but I still think it fits the music (and the collective they belong to). Ultimately "psychedelic" black metal is not something that is easy to identify, not in my view anyway as i don't think psychedelic music is incumbent on having plinky-plonky melotrons and keyboards (which this album obviously has none of).
